WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 255,933, dated April 4, 1882.

Application filed December 1T, 1881. (No model.)

To all whom it may conccrn Be it known that I, WILLIAM BUN'IING, J r., of Boston, in the county of Suifolk and State of Massachusetts, have invented certain new and useful Improvements in Water-Closets; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this application.

My invention relates to a novel construction of thatkind of water-closet contrivancein which the valve through which water is supplied tothe bowl or hopper of the closet is operated by the seat; and my invention consists in a particular or specific form of contrivance in which the two push-bars are adapted to adj ust themselves to any inequality of the plane orlevel of the seat, so as to cause the latter to always come to an even bearing on the two, though it may be hinged so or may have warped out ofshape so that it would not touch both alike were they each arranged in a fixed relationship to each other as to the level of their upper ends.

To enable those skilled in the art to make and use my invention, I will now proceed to more fully explain the construction and operation of the same, referring by letters to the accompanying drawings, in which- Figure lis a front view of a water closet seat embracing my invention, and Fig. 2 is a bottom view of the same.

At Fig. l I have represented the wood-work as if partially broken away, in order to better show the devices located beneath the seat proper of the closet, and in the two figures I have designated the same part of the contrivance by; the same letter of reference.

A represents the upper part, and B the supporting side portions, of the closet, while O is the seat proper, hinged, as usual, at its rearmost edge to the rear part of the top A.

To the under side ofthe top A of the closet, near its front, isl secured a metallic stand, e, in which is pivotally hung, as shown, a lever,f, oneend of which is coupled bya ball-and-socket joint, at t', to the forward end ofa lever, g,which has its fulcrum in a metallic stand, h, (secured to and depending from the under side of A, as

shown,) and the rear end of which is connected by a chain or otherwise to the valve ofthe supply-cistern of the closet. The other end of lever fis pivoted to the middle portion of an equalizing-bar or self-adjusting arm, m, that is formed or provided at each end with an upwardly-projecting rod or finger, 0. The arm or u bar ,m is preferably curved, as shown, (see Fig. 2,) so that its ends are located beneath the front part of the seat proper, O,while its middle pivoted portion lies beneath the front part of the portion A of the closet; and at the localities at which the seat C is supported by the vertical rods or fm gers o said seat is provided with metallic bearing-surfaces p p, against which bear the upper ends ot' the metal fingers o 0, all as clearly illustrated.

The operation of the contrivance shown and thus far described will be understood to be as follows: The natural or normal conditions of the parts being such as represented in the drawings, with the rear end of the main lever g elevated and the front edge of the hinged seat C raised up, when the front part of seat C is depressed by the weight of the occupant the bar m (through the medium ofits fingers o o, on which said seat rests) is moved down bodily, whereby that end of lever fwhich is pivoted to m is caused to descend to the same extent as the bar m and seat C. This action of the lever f causes that end of it which is jointed at t' to the forward end of main lever g to ascend, and thereby said lever gis elevated at its forward end sufficiently to throw the rear end of g down Ward far enough to properly actuate the chain or other device which connects the rear end of g with the supply-valve of the closet.

lt will be seen that the seat, resting, as it does, at its forward part on the two pushbars or fingers o o, placed a proper distance apart, the weight of the occupant of the seat will a1- ways be thrown onto a point in the front of the seatintermediate of the two supporting devices o o, thus avoiding the possibility of any uneven strain on either the seat C or its hinged connections with the closet-top.

It will also be seen that by the use of the arm m, attached merely by the pivotal connection shown to the lever f, the fingers or bars o o projecting up from the ends ofm are always free to, and always will, adjust; themselves Vertically, so that their upper ends will lie in any plane in which the front bea-ring parl; of seat C will come to an equal bearing on them.

/Vhat I claim as new7 and desire to secure by Letters Patent, is-

The combination, with the seat C, the supporting-lingers 0 o, and suitable mechanism for imparting their descending movement to the valve ofthe closet, of means for rendering said fingers o o self-adjusting to any inequality in or changes of the plane of the said seat, substantially as setforth.

In witness whereof I have hereunto set my hand this 14th day of December, 188i.
